Hardware help


I do have installed my Nuki smart lock as below, but even using the shortest lock cylinder, there is a gap remaining in between the Nuki system and the door. I would like to fill this gap using a laser cutted piece of plastic in between the door and the Nuki lock, but I can’t find the exact dimensions and radiuses of the Nuki system. Does anybody have the exact dimensions? The filler piece would roughly look like the sketch below (next post).
